IMPROVEMENT IN SEED-SOWER.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, GOTTFRIED BAXK, ofGreenleaf, in the county of Meeker, and State of Minnesota, haveinvented anew and improved Seed-Sower; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable those skilled in the art to make and use the same, rr-efercncebeing had to the accompanying drawings, forming part of thisspecification.

This invention relates to a new and improved machine for sowing seedbroadcast; and

It consists in a means for scattering the seed, and protecting the samefrom the action of the wind while being sown or scattered upon thegrmuid.

The invention also consists in an improved seed-distributing device, bywhich a greater or less quantity. of seed may be sown on a given area,as required, and seeds of difi'erent sizes sown with one and the samemachine.

In the accompanying sheet of drawings Figure 1 is a side sectional viewof my invention, taken in the line a: x, fig. 2.

Figure 2, a plan or top view of the same.

Figure 3, a rear view of aportion of the same.

Similar letters of reference indicate corresponding parts.

' A represents a suitable frame, which is mounted on two wheels B B, andis provided with a draughtpole, O.

D is aseed-bo'v, secured on the frame A, and extending its whole width,and having a bottom composed of l a series of inclined planes, a, whichform a series of concaves, each of which is perforated with a hole, I).

Underneath this bottom there is a perforated slide, E, which may beadjusted by a lever, F, to regulate the flow of seed through the holes7) into a cylinder, G, underneath, which extends the whole length of theseedbox, and has a rod, H, within it that is rotated by gears c from theaxle of one of the wheels B.

This rod H is llowed a certain degree of longitudinal movement, and isthus moved by a lever, I, for the purpose of admitting .of cavities (Zin the rod being adjusted more or less in line with the holes 11,according to the size of the seed, and the quantity to be sown on agiven area.

The rod H also, by this longitudinal 1nove1nent,ma v be thrown out ofgear when desired, and the seed-distributing apparatus renderedinoperative.

The cavities (l in the rod H are provided with radial flanges c, asshown clearly in tig. l, which serve to discharge the seed throughopenings j, in the lower partof the cylinder G, and througl1,ope11i11gsin a slide, h, underneath the cylinder G, the plate It being regulatedby a lever, J. h

The seed, as it is discharged through the openings g, passes through aninclined narrow box, K, which has a series of rods or pins, 1', fittedtransversely in it.

These rods or pins serve to scatter the seed, and insure the evenscattering or distribution of it upon the ground, while the box Kprotects the seed from the action of the wind.

L represents a series of curved bars, the upper ends of which are tittedloosely on a rod, j, at the rear of the seed-box.

The lower ends of these curved bars have teeth 7;, formed on them,which, as the machine is drawn along, furrow up the ground and cover theseed.

' M is a bar, placed underneath the bars L, and con nected by a link, I,with a lever, N, by raising which,

the teeth 7; may be elevated above the ground whennecessary or desired.

'I claim as new, and desire to secure by Letters Ratcnt 1. The seed orwind-protector and scatterer K, in

combination with the cylinder G, flanged rod H, and.

hopper 1), substantially as described for the purpose specified.

2. The combination and arrangement of the perforated slides E 71,cylinder G, and-rotating rod II, provided with cavities (I,substantially as'and for the purpose set forth.-
